The World Sheepdog Trials in Wales are the Olympics of the herding-dog world. Rather like an open-air ballet, highly trained, highly intelligent dogs move flocks of willful sheep with minimal long-distance direction from their humans. This was the rarefied environment into which Donald McCaig took his Border Collies Luke and June (the Mr. and Mrs. Dog of the title) to compete. His account of how the three of them arrived at this event spans McCaig’s 25 years of raising and training sheepdogs; he not only shares his stories, he provides a valuable commentary on living with and loving dogs.
